Background Structure Functions for Underwater Acoustics,
a basis to Reduce emissions and improve images, is the
dissertation of
Michael Kobold, PE, PhD.
The publisher for the FAU
Ocean and Mechanical Engineering Department is
ProQuest.
My advisor is Department Chair Pierre-Philippe Beaujean, PhD, Professor.
Separate videos of wavefront distortion, for the
Caribbean, Gulf,
and
St. Andrew Bay (using tidal variations) are built from our OCEANS 22 paper data.
The AIP Advances page for Gouy phase in the sea is hopefully adequate to help others do similar analysis.
Here is an errata for it.
The sheet named marketCap of the spectral efficiency calculations from wikipedia pages of the same name (spectral efficiency) show that a tabulation of the market capitalization provides the basis for an estimate that laser-comms has 2200 times the funding that acoustic communications has. One might assume market cap differences are related to research funding differences.

One of the strangest issues involving problems using underwater acoustic modems are the internal waves that are blamed for poor acoustic communications or a complete lack of a-comms. They are more numerous than we might expect, even these exotic nonlinear internal waves:
